Cannot navigate by list items in definition lists in Chromium browsers

[tmthywynn8]

When encountering definition/description lists in Chromium browsers, one cannot navigate by list items (I), however NVDA still provides the list semantics and one can navigate to said list (L). This works as expected in Firefox 126.

Steps to reproduce:

1. In a Chromium browser, open the following by pasting in the address bar:

   data:text/html,<p>Description list with three terms:</p><dl><dt>Term 1</dt><dd>Description 1</dd><dt>Term 2</dt><dd>Description 2</dd><dt>Term 3</dt><dd>Description 3</dd></dl>
   

2. Navigate to the description list by pressing L.
3. navigate by list items by pressing I.

Actual behavior:

{pressing L}: list with 6 items Term 1
{Pressing I}: no next list item

Expected behavior:

{Tested in Mozilla Firefox Version 126.0 (64-bit)}:
{Pressing L}: list with 6 items Term 1
{Pressing I}: Term 2
